Specify the database of the DDL file which was created from the Database combo box. Specify the path of the DDL file we exported in previous step in the File path field.Once we got the DDL file ready, we can then reverse it into ERD. This will extract the schema of your specified database into a script file in the path you specified. Pg_dump -h %hostname% -u %user_name% -port %port% -schema-only %database_name% > %path_to_script_file% PostgreSQLįor PostgreSQL, the database schema can be exported by using the pg_dump command with the following arguments. This will extract the schema of your specified database into the dump file path specified under the dumpfile argument. Oracleįor Oracle, the database schema can be exported by using the expdb command with the following arguments.Įxpdb schema=%schema% dumpfile=%path_to_script_file% content=metadata_only Mysqldump -u %user% -p -no-data %db_name% > %path_to_script_file% Review the selection and press Next to start generating DDL script.įor MySQL, the database schema can be exported by using the mysqldump command with the following arguments.Select ANSI text in the Save as field, then press Next to proceed.Specify the path for outputting the script file in the File name field.Choose Select specific database objects, then choose all Tables in the list and press Next to proceed.Click Next in Generate and Publish Scripts dialog.Right-click on the database which you want to be reversed to and select Tasks > Generate Scripts.Open the SQL Server Management Studio and connect to your database.To generate DDL file for your SQL Server database: Microsoft SQL Server will be used as an example throughout the tutorial. A video demo is also provided at the end of this tutorial. In this tutorial you will first learn how to reverse the DDL file, and then learn how to visualize your database in ERD by reversing engineering the DDL file. support to export the schema of database into a Data Definition Language (DDL) file. So what is the alternative to achieve this, when we encounter this kind of situation? Generating DDL file from DatabaseĪctually, most of the Database Management System (DBMS) such as Oracle, Microsoft SQL Server, MySQL, etc. the production database is not accessible for such purpose). However, what if your database is not accessible to perform the reverse engineering? (i.e. Add functionality with the plugin API.For existing database, ERD can be generated from database schema through reverse engineering. Also included are a query builder, tools for creating, editing, and executing stored procedures, triggers, and functions, a tool to compare table data and/or query results, and SQL history. Some of the main features contained in RazorSQL are visual tools for creating, editing, describing, altering, dropping, and viewing database objects tools for importing and exporting data a database browser for the viewing of database objects and structures and a robust programming editor with support for SQL, PL/SQL, TransactSQL, SQL PL, PHP, Java, XML, HTML, and twelve other programming languages. RazorSQL ships with a built in relational database engine that is up and running out of the box and requires no end user administration. Any other JDBC or ODBC (Windows only) compliant database is also supported. RazorSQL is a SQL database query tool, SQL editor, database browser, and administration tool with support for over 40 databases and built in connection capabilities for Access, Cassandra, DB2, Derby, DynamoDB, Firebird, HSQLDB, H2, Informix, Microsoft SQL Server, MariaDB, MongoDB, MySQL, Oracle, Pervasive, PostgreSQL, Redshift, Salesforce, SimpleDB, SQL Anywhere, SQLite, Sybase, and Teradata. Browse objects with the database browser. Visually create, edit, alter, drop, and view objects as well as import and export data. SQL editor, database query tool, database browser, and db admin tool.
